Summary of Current Radiometric Calibration Coefficients for Landsat MSS, TM, ETM+, and EO-1 ALI Sensors
TL;DR: In this paper, a summary of the current equations and rescaling factors for converting calibrated Digital Numbers (DNs) to absolute units of at-sensor spectral radiance, Top-Of- Atmosphere (TOA) reflectance, and atsensor brightness temperature is provided.

TL;DR: In this paper, the AERONET program of spectral aerosol optical depth, precipitable water, and derived Angstrom exponent were analyzed and compiled into a spectral optical properties climatology.

Revised Landsat-5 TM radiometric calibration procedures and postcalibration dynamic ranges
Gyanesh Chander,Brian L. Markham +1 more
TL;DR: Landsat-5 (L5) Thematic Mapper data processed and distributed by the U.S. Geological Survey (USGS) Earth Resources Observation System (EROS) Data Center (EDC) will be radiometrically calibrated using a new procedure and revised calibration parameters to improve absolute calibration accuracy, consistency over time, and consistency with Landsat-7 (L7) Enhanced Thematic mapper Plus (ETM+) data.
Journal ArticleDOI
Normalized difference vegetation index measurements from the Advanced Very High Resolution Radiometer
TL;DR: In this paper, a global measure of vegetation green foliage dynamics with a measurement precision of ± 10% and a monthly time resolution may not yet meet the exacting needs of some biospheric modelers, but it is remarkable, considering that this possibility was not even conceived when the AVHRR was designed.
